Another object of the invention is the provision of device of this character, wherein the Water supply thereto autonnrtically controlled, While the overflow of such supply is entirely eliminated, thus relieving atten tion. thereto and avoiding the necessity of lillinp," and refilling of said device by an attendant,

A further object of the invention is the provision of a device of this character, wherein the construction thereof is novel in form, so as to occupy the least possible space when in use.

A. still further object of the invention is the provision of a device of this character, wherein the level of Water therein. can be maintained constant, and the possibility of overflow is entirely relieved A still further object of the invention is the provision of a device of this character, 'Wl'llGll is comparatively simple in construction, thoroughly reliable and ellicient in. its purpose, strong, durahle, posse ing hut few parts, automatic in operation, and inexperu sive to manufacture and. install,

l l ith these and other objects in view the invention consists in the features of con rfirluttion, combination and. arrangement of rts, as will he hereinafter more fully described, illustrated in the accompanying thawing, showing the preferred etuhodiment of the invention, and pointed out in the claim hereunto appended.

view

des ates generally a furnace of the hot as. type, which may be of any desired coustruetlon, having; at its top the usual hot air chamber or drum B, the furnace heingr rnerely illustrated in the drawing for the purposes of disclosing the application of and manner of use of the humidifier hereinafter more lully described.

The l1u1nic'....er comprises a Water container or tray 10, preferably made from sheet metal, and of elongated formation, although the same can he of any required size, shape, and made from any suitable material. This container or tray 10, positioned within the hot air chamber or drum B, of the furnace it, so as to rest upon the top l1, ot the air heater of the furnace, as is shown. in Figure El, l. the drawing, 7

Leading in through the body of the furnace A, is a Water supply pipe 12, having a hand operated cut-oil valve 12-3, the elbow 14:, of this pipe losing; extended into the air ehanlher or drum. l3, and tlurougrh the front Wall l5, of the eontaiuruor tray 10, by means of a discharge nestle 16, having; a stepped passage ll, central. thereof. The smaller bore of the ll, at the outlet d of the lflOZZlB l6, formed with. a eled valve seat W, for a valve 19, the pin stem Ell thereof being; loosely ewtagred in the sanaller bore of the passage ll', for sup-- mrtinn; and guiding;- said valve 19, to and from the seat 18, in the nozzle.

Keyed upon and carried by the free end of the nozzle 16, is a substantially 1.;shaped hraclret 21, the horizontal arm 22, of which has pivoted at therein a rocker link 24, forn'led With a medial OlltWit l sted her is adapted to ride upon the surface of the water let into the container or tray 10, and is designed to automatically control the valve 19, for regulating the amount of water to be admitted into the container or tray.

The valve 19, is detachably threaded into a socket piece 28, pivoted at 29,;to the link 24, which latter moves said valve 19, to and from its seat 18, in the nozzle 16, when the armed float 27, is active. The level of the water in the container or tray 10, may be varied by adjustment of the valve 19, in the socket piece 28, although it being-preferable to have the level of water at the point indicated by the dotted line C, in Figure 3, of the drawing.

Leading from the container or tray 10. exteriorly of the body-of the :furnace is an emergency overflow pipe 30, having fitted therein a water depth indicator device in the form of a cup or bowl glhaving a depth equaltojthe depth of the tray 19, and in this "cup or bowl is a floating gauge-rod 32, of the usual type, the device being of the construc tion'ilhistrated 1n F1g'ure5, ot the drawing,

and this device will also serve to enable an attendant-to note at a glance the waterlevel in the container or tray 10, and thus de- .10, by opening the valve 13, in the water supply pipe 12, whereupon water will be caused to vflow into said containerior tray 10, for the filling 'thereof tothe'predetermined level therein, namely as indicated by the :dotted line C,.in Figure 13, of the drawing.

hen the water reaches the proper levelin the container or tray 10, it is autannatieally cut off by the valve 19, becoming seated in the valve seat 18, the valve being clot-red by the operation of the float 27, riding the wafer surface, and in this manner the valve is automatically actuated.

Should an overflow occur in the container or tray 10, the same will be taken care of by the overflow pipe 30, which may extend bero'f a heating apparatus, of a humidifier,

comprising a. water contaiirsr adapted to be located within said chambc 2 a water suppl pipe. a nozzle extending from the pipe nto the container near its top and having a stepped i r ssagc, the free end of the n zzle being formed with a valve seat, a bracket on the nozzle, a. rocker link pivoted to the bracket and confronting the nozzle, socketod pieces-extending in opposite directions from the link, one piece being pivoted to the latter in alignment with the nozzle, a valve adjustably engaged in the pivoted piece to cooperate with the valve seat and having a pin stem projected. into the smaller portion of the passage in the nozzle, a float within the container and connected with the other socketed piece, and emergency overflow mechanism leading from the container.

In testimony whereof I afi'ix my signature.
